I bought 10 cables directly at FTDI; TTL-232R-3V3. They all give 5V output for the supply and 3V3 levels for TTL. Could it be that FTDI changed it since than ? I bought them about 1,5 year ago

Some more background information from the Arduino Pro Mini Quickstart Guide :

The board comes without built-in USB circuitry, so an off-board USB-to-TTL serial convertor must be used to upload sketches. This can be a FTDI TTL-232R USB - TTL Level Serial Converter Cable for the 5V Arduino Mini Pro), or a FTDI TTL-232R-3V3 USB - TTL Level Serial Converter Cable or the SparkFun FTDI Basic Breakout Board for a 3.3V Arduino Mini Pro. One convenient way to connect these is by inserting a six-pin 0.1" male pin header into the end of the FTDI cable or breakout board, and pressing it against the six hole programming header on the Mini Pro.

Hello,
I use an FTDI TTL-232R-3V3 cable to connect my PC to my Arduino Pro Mini 3V3. Problem that I found was that the cable is not providing 3V3 but 5V on the VCC connection ! So in this combination the Arduino is powered by 5V instead of 3V3 that should be....

Or is it me doing something wrong ? Anyone using the same configuration ?

Thanks
